Dynamics of Mangrove Ecosystem along the Nigerian Coastline

by C. E. Isebor, Nigerian Inst for Oceanography and, Marine Research Marine Resources Div, Lagos, Nigeria,



Document Type: Proceeding Paper

Part of: Coastlines of Western Africa

Abstract:

The mangrove brackish water ecosystem along the Nigeria coastline is dominated by the Niger delta and the Astrand coastal area in the east covering an area of about 2003.49 km. Other areas are in the Mahin mud flats in the north western flank of the Niger delta and around Lagos and Lekki lagoons. The mangrove ecosystem is characterized by high humidity, high temperatures and annual rainfall which ranges between 1500 mm to 4500mm with no pronounced dry season. Mangrove swamps are dominated by tidal flats which lie between mean low and high tides. The morphology of the mangrove ecosystem are shaped primarily by longshore currents along the coastline, rivers which criss-cross it from the hinterland, and tidal effects.
